Question

Is it possible to cut multiple dimensions in a php array?

example:
I want the 4th dimension of each first-level element

array(1) {
     [0]=> array(5) 
        { 
        [0]=> string(_) "/opt/path [10823] (/home/path/file.xml)" 
        [1]=> string(_) "/opt/path" 
        [2]=> string(_) "10823" 
        [3]=> string(_) "(/home/path/file.xml)" 
        [4]=> string(_) "/home/path/file.xml" 
        } 
    } 

=>

array(1){ ( [0]=> string(_) "/home/path/file.xml") }

is there an internal php function or a way to achieve this without a loop?

Answer 1

Use array_map :

function selectMyLine($line) {
  return $line[4];
}

$result = array_map("selectMyLine", $data);
print_r($result);

You could alse do the same with array_walk, which directly edit your array instead of creating a new one.
